SARC Pro - Curved Lane Changer Mod

Thanks Gorp for this - yes - I now see my second sentence was a bit ambiguous I should have more precisely stated that ’With the standard stock ARC PRO the signal polarities of lane 1 and lane 2 are reversed with respect to each other.’ Does that help with consistency and interpretation of my post?

Also I agree that my so called ‘Option C‘ is more complex to implement than slot forum simple soldering mod, however Option C enables rapid switching from full digital capability to full analog capability simply by swapping out the two modified track parts with two standard parts. To achieve the same effect with the slot forum mod would, as proposed within the post, require an additional switch and... perhaps some cutting of the brand new ARC PRO enclosure to make the additional switch accessible. Taking this into account the effort is probably reasonably similar for those users who need both full digital and full analog capabilities.

Thanks again Gorp for spotting the ambiguity in my second sentence - much appreciated!

2nd sentence now ok

 

what you seem to forget are the other track pieces you will need to change if you want to switch back to analog

 

yes slot forum will probably need to cut into arc pro to add switch for analog

I’m a bit puzzled by Gorp’s analysis that suggests that other track parts require changing/modification if using the stock ARC PRO in analog mode. Clearly the curved lane changers will require the standard ‘analog to digital’ snips to the flexible pcb tracks - but I would assume this a given and mentioned in one of my earlier posts. Meanwhile, the reason why the slot forum mod is incompatible with analog mode is that it (not surprisingly) results in the two cars driving in opposite directions when in analog mode i.e. unsuitable for analog racing. Would a table showing the pros and cons of options A,B and C add useful value to this topic/subject?

In above post... should read ‘digital to analog’ snips.... apols... :-)

I don't think a table under this topic would help as the options of A and C take in a much broader scope of change than just the curved lane changers.

 

Option B the modification to the curved lane changer as originally started in the thread with acknowledgement of moving the the dead spot to one rail oppersite the exit flipper is the only option giving use of curved lane changers with the ARC Pro powerbase in Analogue or Digital mode at the flick of the switch on the powerbase. And will work in all other situations being backwards compatible. (note the ribbon snip in Option B is different to the orignal analogue snip for C7042) 

 

Option A will void the warranty on the powerbase and render it Digital only due to reversed Analogue power on one lane. It will allow the powerbase to have the same Digital capability as C7042 (Analogue rendered unusable)

 

Option  C will require replacement of a track sections to switch to analogue and the still require the original snip mod on the curved lane changers for analogue use (or better option B mod if you have not snipped the ribbons yet!). and will allow Digital capability as C7042

 

A and C  remove the limitation of Digital track layouts as listed in  https://www.scalextric.com/uk-en/forum/arc-pro-limitations-on-track-layouts/?p=1 

 

A new thread should be started for the pros and cons of different modifications that will affect ARC Pro in a broader sense than just the curved lane changers.

I really like your thinking. As you will have guessed I’m a newbie to forums but have a background in advanced MOSFET research... happy for you to start the new thread and I will certainly contribute... we could link back both to the earlier thread (which we both input into) and this one - alternatively I could start the new thread.. I’m happy either way :-) ... meanwhile... thanks for this recommendation... and, also, for your impressive work with the curve mod as per this thread!

Perhaps the thread title should be ‘Maximising digital and analog capabilities of early production versions of the Scalextric ARC PRO (December 2017)’... would this make sense?

start your own thread drc

blagard started this with his great idea on how to fix curved changers and you started posting your op c on it

Andy should have locked this down immediately

yes like when you started posting on slot forum arc pro mod how to

locked it down they did

so start your own thread

Sorry if I upset you Gorp... my intention here is to help like-minded enthusiasts of Scalextric to get the most out of their new investment in ARC PRO power bases. Meanwhile I happen to believe this product is the most exciting development in SSD since the arrival of the C7030. Amazing and very impressive work by Scalextric and their ARC PRO design team!!! Sorry if this is off topic, but it needs to be said...

Once I figure out how to successfully upload photographs I’ll show the variant of the curved lane changer mod where a single 10mm ‘dead spot’ is formed on the lane changing rail directly alongside the ouput (fixed) flipper/wedge. i.e. a variant of the modification shown in the earliest posts on this thread (acknowledging Blagard-01). With respect to ARC PRO and curved lane changers, I suspect there is very little more to be said...
